The specific manifestations are as follows: after cats smell the smell of other pets on their owners, 1. they will yell at their owners and think seriously. Bite the owner; 2. Ignore the owner, be transparent about the owner's existence, and play by themselves; 3. The cat will be unhappy and lose appetite, and when the owner coaxes the cat, it will lick the owner and leave its own smell.
